Well, Didn't You Know? JKR developed her characters so perfectly that they fall entirely in line with their zodiacal signs!
Which, of course, is proof Ron and Hermione hate each other, and two Leos can't date.
Nevermind that Ron is the strangest Picses I've ever seen.
Bonus mini-"JKR must have read the same site I read!" comment from...bum bum bum! Lockedinaroom! Not to mention the whole thing opens up with an "H/G is incestuous!" comment.
Thanks to a quiet, shy mouse on wank report. Now, astrologers, bust out yer charts!
